4 Claims.

This invention relates to a combined wash basin and urinal of a sanitary type, compactly arranged, for use in toilet rooms of necessarily restricted dimensions, particularly in airplanes, where only minimum space for toilet purposes is available.

This invention has as its principal object the solution of the problem of equipping small rooms with such fixtures, not only by combining the wash basin with the urinal, but also by providing the wash basin, which projects out from the supporting wall a substantial distance beyond the urinal, with a hinge support whereby it may be swung up out of the way when it is desired to use the urinal. The hinged supportof the wash basin permits the saving of over four inches in the width of the aisle or passageway provided in front of the wash basins, which is an important consideration in airplane design. By making the front of the wash basin project a substantial disiance beyond the front of the urinal, whoever wishes to use the urinal must first swing the wash basin up out of the way, thereby preventing the user from soiling the front of the wash basin.

A further object of the invention is to provide the hinged wash basin with apertures in the walls of the drainage portion of the wash basin, whereby the water used for washing the han s also flushes. the interior surfaces of the urinal positioned beneath the center and rear portion of the wash basin. The apertures for flushing the interior surfaces of the urinal, when combined with the necessity for swinging the basin up out'of the way to gain access to the urinal, prevents soiling the exterior surfaces of the urinal, and has the advantage of providing a sanitary arrangement j which will satisfactorily eliminate one cause of characteristic toilet odors.

] Ajf'urther object is to provide a hinged wash ,'"basin having means for readily and effectively latching the hinged wash basin in either i s ra ed or lowered position, to prevent sudden or lurching movements of the airplane, due for example to storms or a rough landing, from tearing the wash basin from its support or from damaging the hinges.

An additional object is to provide a hinged wash basin with a depending substantially cylindrical wall forming a spout, a bottom wall covering the opening of said spout, the rear half of the depending wall having spaced apertures both for directing streams of wastewater laterally and rearwardly from the spout against the upper inside surfaces of the rear and side walls of the urinal positioned beneath the basin, and for completely draining the spout of residualwastewater as it is swung upwardly about its hinge. A relatively large drainage aperture is provided in the bottom wall of the spout, and an additional aperture is provided in the lower front edge of the spout, said additional aperture extending downwardly and forwardly for directing a stream of the waste water against the upper inside surface of the front wall of the urinal.

In the drawing:

Figure l is a partially isometic perspective view showing the hinged wash basin and urinal in different positions of use;

Figure 2 is a side elevational view, partially in section, taken on the line 2-2 of Figure 1;

Figure 3 is a plan view of the hinged wash basin in the position seen from line 3-3 of Figure 1;

Figure 4 is a vertical cross section taken on line 4-4 of Figure 1;

Figure 5 is an enlarged side elevational detail view of the depending spout of the wash basin; and

Figure 6 is a horizontal cross section taken on line 6-6 of Figure 5.

Referring to Figures 1, 2, and 4, the wash basin I0 is supported by a horizontal barrel hinge II on the wall or partition l2 of the washroom. The basin III has a top flange l3 provided with a finishing rim l4, and depending bowl l5 having a depending spout It for draining the waste water from the bowl. The side wall of the spout is substantially cylindrical in shape. A plate l1 covers the opening at the bottom of spout l6 and forms its bottom wall. Apertures l8, l9, and 20 are provided in spout I6 for simultaneously draining the waste water from bowl l5 and flushing the inside surfaces of the wall 22 of the urinal 2|. The urinal 2| is supported on partition l2 beneath the rear portion of basin l0, and has a drainage nozzle 23 to which a hose (not shown) or other conduit may be connected for properly disposing of the waste fluids.

As shown in Figures 2, 5, and 6, drainage aperture 3 extends vertically and is, located in the bottom wall I! of spout l6, while aperture l9 extends downwardly and forwardly through the lower front edge of spout I6 where bottom wall l1 joins the side wall of said spout. The streams of waste water draining through apertures l8 and I9 will flush the upper inside surfaces of the front portion of wall 22 of urinal 2|. Spaced apertures 20 extend radially and horizontally through the rear half of the side wall of spout I6 adjacent the bottom wall ll. The st ea s of waste water draining through these apertures are directed laterally against the upper inside surface of the side and rear portions of wall 22 of urinal 2|. This arrangement of apertures l8, I9. and 20 serves to keep down characteristic toilet odors by using the waste water from the wash basin for repeatedly flushing those inside surfaces of the urinal walls most likely to be soiled. Apertures 20 also serve to completely drain any water remaining in spout I 6 while basin I0 is being swung around hinge ll into its raised position.

As shown in Figure 2. wash basin I0 is arranged to extend a suflicient distance beyond the front of urinal 2|, so that the opening into the urinal is largely concealed from the user. This requires the user to swing the basin up out of his way to gain convenient access to the opening into the urinal, thereb preventing the user from soiling the exterior of bowl I! in most cases. This also serves to keep the wash room more sanitary and free of characteristic odors.

It is found necessary to latch wash basin securely both in the raised position shown in Figures l and 4, and in the lowered position shown in Figures 1 and 2, to prevent sudden or lurching movements of the airplane from tearing the basin from supporting wall l2 or from dampging hinge ll.

A suitable latching meansfor the raised position of basin I is provided by the elongated projection 25 on the central front portion of rim ll, said projection 25 being forced beneath and behind a cooperating roller 26 mounted between the yoke arms of bracket 21 attached to the wall |2. The roller 26 is formed of a yieldable material such as .rubber and firmly presses the top flange l3 against stop 28 formed by recessing said yoke arms of bracket 21.

A suitable latching means for the lowered position of basin I0 is provided by spaced spring-like retaining brackets mounted on wall l2, said brackets 30 detachably engaging the spaced rubber rollers 3| mounted on depending side skirts 32 by means of journal brackets 33. Each skirt member 32 tapers in width from the rear to the front and is secured along its upper edge to one side of rim l4, thereby serving to strengthen top flange l3. Each journal bracket 33 consists of an elongated metal strip bent to the shape shown in Figures 1 and 3, and having its spaced ends rigidly secured to the inner surface of a skirt 32, thereby serving to strengthen the skirt. The rear end of each journal bracket 33 is bent into a U- shape for rotatably mounting the axles of a roller 3|. By rotatably mounting latching rollers 3|, the effective life of the rollers is prolonged since there is less sliding contact between the roller 3| and retaining brackets 30, and also since the brackets 30 contact a different place on the surface of rollers 3| in successive latching operations.

Our combined hinged wash basin and urinal is also adapted to be arranged in the corner of a washroom, and still obtain most of the advantages described for the basin l0 and urinal 2| which are mounted on only one wall. In the isometric perspective portion of Figure 1, urinal 35 is shown attached to a supporting plate 36 secured at one edge to wall l2, and at the other edge to partition wall 31. The wash basin 38 is similar to basin Ill, but differs from basin Ill in the form of latching means employed for retaining the basin in its lowered position, and in the location of the side wall drainage apertures. Said latching means comprises a U-shaped spring clip 39, secured underneath one edge of the basin, for

detachabl engaging a pair of rollers mounted side by side on a wall bracket 40 mounted on wall l2, as is obvious from the drawing. The latching type basin arranged to be hinged to wall l2, and latched at one side to partition 31.

In the invention as shown at the left of Figure 1, the dimension perpendicular to the axis of hinge H, and indicated at D, may be reduced at least as much as four inches over the present practice of rigidly mounting a wash basin over a urinal. While this saving in space is an especially important consideration in aircraft design, it will also be found to have merit in the construction of washrooms in railway coaches, or in any building location where only minimum space for the aisle or for the washroom is available.

It will be understood that the wash basins will be provided with any desired form of water supply, provision for overflow, andstoppers.

We intend the claims to cover all changes and modifications of structure which may be fairly regarded as coming within their scope.

We claim:
